Rust Surface Preparation

Surface preparation is vital to effectively painting your rust stained surfaces. All surfaces have got to be clean and dry. They should also be free from anything that can interfere with the adhesion of the coating. The best way to remove loose or failing material is to scrape or brush it off with a stiff bristle brush to a sound edge and then feather the sound edges with a fine grade abrasive paper. Be sure to completely remove all dust when performing this action. Dust can cause problems when you apply the paint or coating.

Remove Organic Growth

Make sure that you remove all visible signs of organic growth. We recommend treating these areas with VC175 Tropical Strength Mould Killer. Allow it to dry. This will help to prevent the mould from growing in that area again and causing further problems to your surfaces. If there are still areas that have sound paint (meaning paint that isn’t damaged or contaminated), clean it down with a product like our Rust-Oleum ND14 Cleaner and Degreaser, which removes all contaminants from the surface. After you have performed these steps, rinse your coating with clean water. This will remove all residues and allow it to dry.

Degrease The Surface

Thoroughly degrease the surface with methylated spirits. You can purchase these in most local supermarkets. You should also change the cloths regularly. This ensures that you don’t further contaminate the surface with a dirty cloth. It is best to fill any cracks and small surface defects with a suitable filler too. This prevents further cracking or other damage to the surface itself. Once degreased, allow it to dry, rub it down with a fine grade abrasive paper and remove all dust. After these steps have been carried out, it is best to prime all bare and filled areas with one coat of one of our primers, such as our Acrypol Zinc Phosphate Primer. It is important to allow a minimum drying time of approximately two hours in normal drying conditions. This is to ensure that the area is completely dry.

Interior & Exterior Decoration

For interior decoration, it is best to decorate with an interior paint such as Zinsser Perma-White Interior, apply two coats but be sure to allow a minimum drying time of 2 hours between each coat application. For exterior projects however, use a paint like Zinsser Perma White Exterior, two full coats should do the trick and, once again, allow a minimum drying time of at least 2 hours before applying the second coat. This will help your surfaces to have that crisp and clean look that many property owners strive for.
